Intestinal metaplasia (IM) have long been thought to play a role in the pathogenesis of gastric intestinal adenocarcinoma, but not in that of diffuse cancer. We studied 20 normal gastric mucosa, 90 IM, 39 atypia (dysplasia or adenoma), and 51 adenocarcinoma to evaluate the expression of p53, erb B2, and H-ras p21 proteins and to assess the correlation with IM (esp. type III IM, revealing positive HID-AB/PAS for sulfomucin). Positive rate of HID-AB staining revealed an increased trend in comparison between IM, atypia and adenocarcinoma. It was the highest in mucinous carcinoma, but it was not correlated with positive oncoprotein expressions. Positive rates of oncoproteins revealed increased trends in comparison between IM, dysplasia or adenoma and adenocarcinoma in c-erb B2 and p53 (P<0.01). The positive rates were highest in intestinal adenocarcinoma (50.0% and 54.2%, respectively). Rates were lowest in biopsy tissue of IM (4.4% and 8.7%, respectively). The expression of H-ras p21 was not significant in gastric carcinogenesis. There was no significant correlation between oncoproteins and other clinical parameters, such as depth of invasion, differentiation, size and nodal metastasis of the tumors. Therefore, we suggest that p53 and erb B2 may play a role in the carcinogenesis of gastric intestinal adenocarcinoma.

Retinoblastoma is a malignant tumor that arises from the retina. The prognosis is very unfavorable if the choroid is affected or the central nervous system is invaded or if metastasis have occurred. We experienced a case of the retinoblastoma with optic nerve involvement in a 3-years-old female had metastasis to the tibia. She was enucleated of the left eye five months ago. We report it with brief review of the literature.

PURPOSE: Conventional laparoscopic appendectomy (LA) is a widely used treatment for appendicitis. Nowadays, single incision laparoscopic appendectomy (SILA) is increasingly used as an alternative treatment for appendicitis. The purpose of this study is to evaluate the clinical significance and differences between LA and SILA. METHODS: A total of 519 patients undergoing LA or SILA between January 2011 and December 2012 were identified in a retrospectively collected database. Patients' characteristics and peri-operative variables were analyzed. RESULTS: LA was performed in 485 patients and SILA was performed in 34 patients. Mean operation time for the LA group was 62.7 minutes (range 23.3~68.1) and that for the SILA group was 62.7 minutes (range 50.9~74.5). This difference of operation time was statistically significant. In the learning curve of SILA, operation time was gradually decreased. No significant differences in hospital stay and peri-operative complications were observed between groups. CONCLUSION: Although operation time for SILA was longer than that for LA, SILA was safe. Therefore, a prospective study should be conducted in order to confirm the possibility of application to most appendicitis patients.

OBJECTIVE: The aim of this study was to assess the relationship between disease progression and expression of c-erbB-2 and S-100 protein positive dendritic cells in Cervical cancer. STUDY DESIGN: Tissues were analyzed from 100 patients. Each of them had invasive carcinoma(44), microinvasive(12), CIS(33), CIN(II) before treatment, c-erbB-2 oncoprotein expression and S-100 protein positive dendritic cell were confirmed by immunohistochemical staining. (Avidin-biotin complex method) RESULTS: C-erbB-2 immunostaining was significantly associated with disease progression (p<0.05). In case of CIN I, there was not noted stained specimen but in case of invasive carcinoma, 24 cases of stained specimen were noted. S-100 protein positive dendritic cell was not associated with disease progression of cervical carcinoma.(p>0.05) CONCLUSIONS: According to our results, c-erbB-2 is possible factor in Carcinogenesis of cervical carcinoma with progression of it. and S-100 protein positive dendritic cell was not associated with disease progression of cervical carcinoma.
